IMPROVEMENT IN COOKlNG-STOVES.

Specification forming part of Letters Patent No. 53,497, dated March 27,1866; antedated January 10, 1866.

To all whom it may concern."

Be it known that I, JAMES SPEAR, of the city and county of Philadelphiaand State of Pennsylvania, have invented a new and useful Improvement inAsh-Sieves for Cooking Stoves and Ranges; and I do hereby declare thatthe following is a full and exact description thereof, reference beinghad to the accompanying drawings, and to the letters of reference markedthereon, making apart of this specification, in which- 7 Figure 1represents a plan view of the stove with the doors to the ash-pit open;a, the guide-plate for the ashes; b, the sieve; c, the ash-pan; D D, thedoors; E, the side of the box; F, the handle to shake the sieve. Fig. 2represents a sectionalview of the same, with the doors to the boxremoved; Fig. 3, a sectional view, with the ash-sieve and ash-paninclosed, and the hearth-plate K in its place. Fig. 4 represents thehearth of the stove with the ash-pit removed; Fig.5, the sieve; Fig. 6,the ash-pan; Fig. 7, frame or carrier for the sieve]; Fig.8, thepartition-plate between the front of the oven and the back part of theashbox G; Fig. 9, the ash-sieve inclined; Fig. 10, the side-plate of thestove and ash-box combined, H and E; Fig. 11, the bottom plate of thestove and the bottom of the ash-box combined, I and L.

The nature of my invention consists in providing a cooking stove orrange with a large box to receive the ashes and a ready means ofseparating the unburnt coal from the ashes after they are drawn from thefire-chamber and before they are removed from the stove, and also aneasy mode of removing both the ashes and unburnt coal from the stoveafter they are separated.

To enable others skilled in the art to make and use my invention, 1 willproceed to describe more fully its construction and operation.

Take any of the well-known large-oven cooking-stoves with elevatedhearths, such as the Wellington or Columbia cook-stoves, and remove thebottom of the ash-pit or hearth, as is shown in Fig. 4, and in placethereof extend the bottom plate J, Fig. 11, of the stove on a line withthe front part of the hearth, forming a bottom for the ash-pit or box,and in front of the box or ash-pit place doors D D, as is shown in Figs.1 and 3. The sideplates of the stove being extended, as is shown in Fig.10, letter E, forms sides for the box or ashpit, and in this inclosedbox place a sieve in an inclined position, resting on a frame, Fig. 7,to which frame a handle is attached, extending through the side of thebox, as is shown in Fig. 3, letter F. This frame is supported by a bar,0, Fig. 9, running lengthwise in the box, and lugs S S, Fig. 8, on thepartition-plate G. By taking hold of the handle F, Fig. 3, and moving itback and forth with arapid motion, you vibrate the sieve and cause theashes to separate from the nnburnt coal. The box or ash-pit, beingentirely closed, as shown in Fig. 3, no dust can escape into the room,asthe heat from the fire and the suction of the chimney form a vacuum inthe box, thereby causing the finest particles of ashes to become, as itwere, a piece of lead, which falls immediately into the ash-pan. Uonse-.

quently no dust can possibly escape. The sieve and ash-pan beingentirely inclosed, as is shown in Fig. 3, is a decided improvement on mypatents of l ebruary 19,1861, and April 15, 1862. Again, the sieve beinginclined, the unburnt coal will roll by the motion of the sieve to thefront part of the sieve, and will allow the ashes to fall through thesieve more easily than when the sieve lies in a tlat position.

Having thus fully described the nature of my invention, what I wish tosecure by Letters Patent is 1. The application of an inclined sieve,whenapplied within the limits of a stove or range, as shown and described.

2. The sieve B, the doors D, the hearthplate A, the partition-plate G,and frame L, arranged and combined substantially as described.

3. The bottom plate J and L, when arranged in combination with thepartition-plate Gr and hearth-plate A, as shown and described.

4. The inclosed sifting-pan B, capable of beingvibrated, in combinationwith an ashpan, O,when both are applied to a stove or range, as shownand described.
